The Acute Stress Response in the Multiomic Era

Area of Science:

• Neuroscience
• Molecular Biology
• Endocrinology

Background:

• The acute stress response (fight-or-flight) is crucial for survival.
• Chronic stress leads to allostatic load, causing disease.
• Molecular changes from acute stress are less understood than chronic stress.

Purpose of the Study:

• To explore molecular cascades triggered by acute stressors.
• To propose a framework for interpreting multiomic data on stress.
• To identify molecular correlates for allostatic load.

Main Methods:

• Review of signaling cascades and molecular changes from acute stress.
• Reanalysis of multiomic screen data from rodent hippocampus and amygdala.
• Theoretical framework integrating multiomics, energy homeostasis, and gene regulation.

Main Results:

• Acute stress rapidly induces specific molecular and signaling changes in the brain.
• Multiomic data analysis reveals patterns related to stress response.
• Identified challenges in experimental design and data analysis for stress research.

Conclusions:

• Deep molecular profiling of acute stress can offer insights into allostatic load.
• Understanding acute stress molecular mechanisms is vital for predicting adaptive or maladaptive responses.
• Future research should focus on multiomic approaches to unravel the stress response.
